Gets or sets a value indicating
whether messages should be searched starting with the most recent
messages first. The server imposes a limit on the number of
messages that can be returned in a chat history query. This
property can be useful in reducing the amount of paging which is
necessary when the target message occurred recently.

Gets or sets the search string.
The search string may consist of one or more space-separated words,
each of which will be treated as a search term. If the property
MatchCaseSensitiveis
true, this search will be case sensitive. If the property
MatchExactPhraseis
true, the entire search string will be treated as a single
search term.

Gets or sets the starting
message ID for this query. If this value is set to a non-zero
value, the
DateBeginningand
DateEndingproperties will be ignored, and the search will be performed
relative to the specified message. Use this parameter to retrieve
an additional page of results when a search returns
ExceededServerLimit.
